Speaking based on my experience, Luffy tend to fk up stuff in
the One Piece world. Example:Luffy cooking in the recent episode.
However, if his naïve
& childish nature was completely removed from his
personality, what do you guys think will happen instead?

From what i see, she started to hate the World Government &
possibly the people of her town because they tricked her saviour,
Fisher Tiger into a death trap. Is that the main reason why she
joined the Revolutionaries?

PS : I wanted to add this on the koala page but was afraid
that it might get undone, since its speculation after all.
